!! [[Film/{{Onmyoji}} Film]]

* HoYay: Seimei and Hiromasa. ''Seimei and Hiromasa''. "Oh, I don't care about the world, but I'll save it if ''you'' really want me to."
** Comes up in the sequel too. They ''really'' don't want each other to die.
* MoralEventHorizon: [[spoiler: Genkaku didn't seem all that disturbed when he offers his children up as sacrifices to the gods or when he kills his wife.]]

!! Video game
* BigLippedAlligatorMoment: The dream Seimei has [[spoiler: in which he kills Kagura]] at the beginning of episode 11 can be viewed as this. Neither is it mentioned again nor does it play any important role in the story.
* TheComputerIsACheatingBastard: [[spoiler: Let's face it, Computer[[note]]or Smartphone in this case[[/note]] Ōtengu in chapter 18's battle against Kuro Seimei is ''unbelievable''. Nowhere else in the game do you find anyone with ''two'' special ''[[RareCandy mitama]]'' effects at once.]]
* CrowningMomentOfFunny: [[LargeHam Yōko]]'s defeat at the end of chapter 7. ''Kooooon kooooon'', indeed.
* FoeYay: Believe it or not, the moment when [[spoiler: [[ScrewYourself Kuro Seimei chokes Seimei]] in chapter 18]] can be viewed as this.
* GaryStu: Possibly Seimei himself, in which case it is ''completely'' [[JustifiedTrope justified]] in that [[spoiler: all his bad traits have been [[LiteralSplitPersonality extracted from him and embodied as another person]].]]
* HoYay: The Hair Eater is confirmed to be in love with Seimei in canon. It surely doesn't help matters that his sister is [[ShipperOnDeck completely supportive]] of this.
** Ibaraki-dōji's unquestioning and, frankly, ''masochistic'' loyalty toward Shuten-dōji comes off as this. Made even more obvious by this [[https://youtube.com/watch?v=AVtZh3LP7dc Valentine's Day mini-drama]] in which it is revealed that Ibaraki-dōji was the one sending Shuten-dōji alcoholic chocolates instead of Momiji.
* IncestYayShipping: The Mujō brothers are frequently shipped together, thanks to the (probably unintentional) IncestSubtext in canon.
* NightmareFuel: Google Play Store places this game in the Horror genre for a reason. Many ''yōkai'', case in point [[CreepyChild Ushi-no-koku-mairi]] and [[LiteralManeater Kijo Momiji]], are bound to give you chills.
* NoYay: Any pairings involving Aobōzu whose occupation as Buddhist priest requires him to be celibate. Not that this stops his fans from having imaginations anyway, thanks in part to his [[{{Bishonen}} appearance]].
** [[spoiler: [[FoeYay Kuro Seimei]] [[ScrewYourself and Seimei]], ''full stop''.]]
* ThatOneBoss: [[spoiler: The despicable, undefeatable abomination from Hell that is ''Kuro'' friggin' ''Seimei''. The dude himself isn't ''that'' strong, it's his band of supporters that are Sanbi-no-kitsune, Ōtengu and Yuki-onna that makes the battle against him qualify. And no, Kuro Seimei is ''not'' the FinalBoss, since the story does ''not'' end with him.]] Before that, the earliest That One Boss appearing in the game could be Ibaraki-dōji aided by ''three'' Shuten-dōji, good grief, at the end of chapter 11.
* ShipsThatPassInTheNight: The Ōtengu/Yōko pairing is surprisingly popular within the fandom even though plot-wise they have never met [[spoiler: and will never meet, now that Ōtengu is dead in chapter 18.]]
* {{Tearjerker}}: The second chapter.
* TheissTitillationTheory: Or how else would you explain how [[MrFanservice Yasha]]'s {{Stripperiffic}} post-Awakening outfit hasn't fallen off yet?
* ViewerGenderConfusion: It is very easy to mistake Shirodōji and Kurodōji for girls until you hear their voices. There have also been fans who mistake [[LongHairedPrettyBoy Yōkinshi]] for a female character.
* WTHCastingAgency: Many fans have this reaction towards Creator/TakehitoKoyasu in the role of [[AnimateInanimateObject Chōchin-obake]].
